Dear friend,


In steelmaking, every temperature reading affects quality and cost. Unstable thermocouple performance or sampler inconsistencies can lead to rework, waste, or even safety risks.


That’s exactly where we’ve been helping mills for nearly 30 years.


I’m Marada Guo from Tianjin Aolite. Since 1996, we’ve focused on disposable thermocouples and steel samplers – not as a commodity, but as a reliable tool for your daily operations.


A few things our clients in India, Turkey, and Brazil appreciate:

Consistent output – We make 10 million thermocouples and 5 million samplers per year, so you never face supply gaps.

Better welding precision – Our fully automated PtRh wire welding (comparable to Her****) helps lower your cost per reading.

Flexibility – Tube length, type B/S/R/W, models 602/603/604 – all can be adjusted to your lance system.

One less vendor to manage – We also supply oxygen probes, hydrogen probes, contact blocks, and cables.

Would you like to see our latest catalog? I can send it directly – no obligation, just a reference for your team.

Feel free to reply with “catalog” or simply ask me anything about thermocouple/sampler specs.

Best regards,
Marada Guo
